I would like to get some equations for generating fractal
images in color.  Its for an art project I have in mind
for Harvard Square in Cambridge, Massachusetts.  I want
to do a sidewalk fractal painting on the sidewalk.  So
what I need to be able to do is to generate a matrix of
how each point in the painting should be colored.  For
example, starting with a 100 X 100 matrix, which of 7
colors should be painted on each box/brick?  Here's a
picture of part of the matrix:

     gbb...
     ggb...
     ggg...
     .
     .
     .

where g stands for green, b for blue.  I would like to
have some simple equations that can be made part of a
BASIC program that I can run on a VAX or IBM compatible.
